Having a unique focus on fluorescence instrumentation for over 40 years and customers throughout the world, Turner Designs is the leader in filter fluorometer design, manufacturing, and support.

Providing solutions to researchers, monitoring agencies, system integrators, spill response teams, and ship owners, Turner Designs is known for providing rugged, reliable and stable instruments. We provide submersible, field, handheld, laboratory, and online fluorometers and turbidimeters varying in functionality, size and price to fit any type of user need. In addition to holding several patents for product innovations, we continuously focus on quality and repeatedly receive very high customer ratings.

Our applications team provides pre-sales support to help customers identify instrument requirements as well as post-sales support to assist with implementation. Our modular instrument design enables us to easily adapt our instruments for custom applications and system integrations. Our on-site manufacturing team with an average tenure of 18 years provides leadtimes as short as 1 week while still meeting our committed delivery dates over 98% of the time.


Turner Designs is continuously expanding our repertoire of optical instruments to meet new application requirements. Standard optical configurations include in vivo and extracted Chlorophyll, blue-green algal pigments such as phycocyanin and phycoerythrin, active fluorescence for measuring fluorescence yield in marine research as well as ballast-water compliance checking, Dissolved Organic Matter (Algal as well as Terrestrial), ammonium, optical brighteners and tryptophan for wastewater monitoring, dye tracers, and crude and refined oils as well as infrared wavelengths used to detect turbidity. Custom optical configurations are readily available for most packages. Standard package configurations include submersible, handheld, field, laboratory, online, and configured for integration into vehicles. Data acquisition is available real-time and through several datalogging possibilities. Submersible instruments can be configured for depth profiling, long-term monitoring and horizontal mapping with GPS-integration at depths up to 6000 meters. Solid Secondary Standards which enable quick instrument verification and calibration checks are available for most applications and are known to hold their value over several years of usage.
